My random rumblings

Something of everything and nothing at all

Text search in large files

13. May 2021 Daniël (0)
It is not always possible to open large files with a text editor and sometimes it is good enough to know that data exist within a file.

You can use the following PowerShell command:
Select-String -pattern "Text Pattern" -path <FilePath>

Select-String -pattern "10016672" -path .\mprdata.xml

Analysing Memory Leaks in .NET

26. August 2020 Daniël (0)

To determine if an application has a memory leak add the .NET CLR Memory Windows performance counter. You need check for a trend over a long period of time rather than the immediate values.

Make a memory dump of the application.

Open WinDbg.

Click on File and then on Open Crash Dump.

Type the following commands:

lm

.load C:\windows\Microsoft.NET\Framework64\v4.0.30319\sos.dll

.sympath SRV*c:\localsymbols*http://msdl.microsoft.com/download/symbols

.symfix

.reload

!dumpheap -stat

 

From the above you should see which objects have excessive number of items, with the following you should get the addresses of the object:

!DumpHeap -type <TypeName>

Use the following to see what keeps this object in memory.

!GCRoot <Object_Address>

My notes from a TED talk.

We make everything that is uncertain certain.
Religion has gone from faith and mystery to certainty.
I am right and you are wrong shut up.
We need to love with out whole hearts even where there is no guarantee.
Accept your vulnerability
I am enough
Vulnerability is essential to living whole heartedly.
Vulnerability is not weakness.

shifting baseline syndrome

Broadly, the effect is called “shifting baseline syndrome,” and it’s what happens when gradual, long-term change meets the dumb, immediately gratifiable human brain. - Adam Rodgers
